2004 Orionid Shower

2004 OrionidsThe annual Orionid meteor shower occurs when debris from Comet Halley intercepts the Earth at a high velocity. This debris stream is somewhat diffuse, so we see activity for several days on either side of the peak. The Cloudbait allsky camera recorded several bright Orionids per hour every night for a week before the shower maximum on October 21.

This is a composite image of 103 meteors collected on the evenings of October 19-21. Because the images were collected over many hours, the radiant of the shower is not clearly seen.

Long necklace-like streaks are stars or planets captured as they traveled across the sky over many hours. These form arcs centered on Polaris, which is located fairly low in the sky above the zero degree azimuth marker.
